Hi All- This is my first post. I just ordered a Model S and am in my one week grace period. I have thus far selected the standard sound system based upon past posts in this forum that suggest there is little advantage to the premium sound system. Have there been any changes to the premium sound system in the updated 2016 Model S to make it worth now considering? It doesn't seem that any features have been added so my question is mainly in reference to the acoustics. Thanks in advance for your advice.
